Summary:
In this paper, we constructed column weight two parity-check matrix by imposing pre-defined target girth and code length while maximizing code rate. Then this constructed binary parity-check matrix is transformed into non-binary matrix by using a randomly generated elements in Galios field GF(q), where q=2,4,8 and 16. We investigate bit-error rate performance (BER) for higher orders of Galios field GF(q) as compare to its binary counterpart. We found that for column weight two LDPC codes higher orders of GF(q) substantially improve BER performance and converge early than lower values of GF(q).
